The next generation of Merrell's Hydro Moc, sure to divide opinion among advocates of Merrell's amphibious EVA creation, it has grown a maximalist sole and its overall shape is slightly more measured and modernised. With a striking reptilian appearance, its amphibious design means it’s perfect for trails that head in and out of water. Moulded from a single-density injected EVA contoured arch, set atop a chunky shock absorbing midsole for all-day comfort.
